Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9TK4/D3V - Bosch Rexroth R901335747

If the pilot pressure fluctuates, the characteristic curve of a proportional valve changes with it. The 4WRZ10E1-85-7X/6EG24N9TK4/D3V keeps it constant through an integrated pressure reducing valve and controls 85 l/min nominal flow.

Benefits

• Integrated pressure reducing valve for a steady pilot stage pressure.
• External pilot oil supply with internal drain, the pilot stage does not depend on the pressure at port P.
• 85 l/min nominal flow, up to 170 l/min at 315 bar maximum operating pressure.
• Spool symbol E1, three switching positions, four ports, 24 V DC.
• FKM seals, concealed auxiliary actuation, mass 8.26 kg.

Applications

The valve is fitted on axes whose system pressure drops during the cycle, for example on presses with an accumulator circuit. The concealed auxiliary actuation allows the mechanics to be checked without connected electronics. Subplate mounting follows ISO 4401-05-05-0-05.
